After spending much of October driving around and taking pictures on Matijevic Hill, Opportunity hunkered down for Halloween and spent the holiday quietly, staying out of mischief's way and the Mars Exploration Rovers (MER) mission roved another month closer to its ninth anniversary of working on the surface of the Red Planet.

Welcome to my monthly survey of the activities of robots across the solar system! Tomorrow is the equinox at Mars; both Curiosity and Opportunity will be spending the month actively analyzing Martian rocks. It'll be a less active month for Cassini, as Saturn passes through solar conjunction late next month.
